IMPROVEM ENT lN TOBACCO-PIPES.

Specification forming part of Letters Patent No. 34,5g5, dated March 4,1862.

.To aZZ whom it may concern:

Be it known that I, A. D. MILNE, of Tiverton, in the county of Newportand State of Rhode Island, have invented certain Improvements inTobacco-Pipes, the construction and operation of which I have describedin the following specification and illustrated in its accompanyingdrawings with sufficient clearness to enable competent and skillfulworkmen in the arts to which it pertains or is most nearly allied tomake and use my invention.

My said invention consists in, first, providing the stern of atobacco-pipe with a removable metallic condenser, substantially ashereinafter described, for the purpose of cooling the smoke andcondensing the essential oil of tobacco therefrom as the smoke passesthrough the stem; second, providing the bowl of the pipe with aremovable lining constructed in the manner hereinafter described, incombination with a removable partition in said bowl, as set forth;third, providing the stem with a valve which may be opened to admitatmospheric air or closed at the pleasure of the user, the same beingconstructed and arranged as described, and operating in the'manner setforth.

/ 3 forming the center, and being surrounded by the fine wire-gauze4.The wire 3 extends the whole length of the body or main portion of thestem, and furnishes a convenient means of withdrawing the whole of thecondenser when desired. The gauze is formed around it in such a manneras to present cylindrical sections sufficiently large to nearly or quitefill the bore of the stem, as shown, the warp of this cylindrical gauzebeing returned at intervals upon the wire 3, as shown at 5 5, andsecured to the said central wire by winding fine wire around it. By thisarrangement the smoke is partially deflected alternately to and from thecenter between each two contiguous sections, and the more effectiveoperation of the condenser thereby secured, the convergence anddivergence of the warp between the sections of gauze having a tendencyto produce this effect. The upper section or portion of the cavity isrepresented as being made cylindrical, this form being preferred, thoughother forms may be used, if desired. About two-thirds of the way down tothe bottom the cavitty is abruptly diminished in size, so as to form ashoulder to support the partition 7. This partition is perforated toallow the smoke to pass through it. The portion of this cavity below thepartition may be filled with a sponge, 8, to absorb the impurities and aportionof the oil from the tobacco; or a wad of cotton might answer thesame purpose less perfectly. The aperture 9, through which the smokepasses into the stem of the pipe, enters the bowl near the top of thesponge, but so arranged that the smoke passes through the sponge in itsegress from the bowl. I i

To prevent the sides of the pipe becoming coated by use, so as tointerfere with the removal of the partition 7, I provide the upper partof the bowl with a removable metallic lining, 10, which extends down tothe partition. It will be observed that a considerable opening is madein the side of this lining at 11, and the construction is the same uponthe side opposite. This, while it furnishes a convenient means ofgetting hold of this lining for the purpose of removing it, alsofurnishes a means of cleaning the sides of the pipe by turning thelining around within it, the edges so formed scraping off the coatingwhich may have adhered to the bowl. The narrow strips which form thelower portion of this'lining may be extended down by the sides of thepartition and returned a short distance under it to furnish a convenientmeans of removing the partition, if deemed preferable. 12 is a valveattached to the 'stem of the pipe, and opening into it, to enable theuser to modify the strength of the smoke and increase the effect of thecondenser by admitting atmospheric air. At the time of lighting thepipe, or at any other time when pre ferred, this valve may be closedeither wholly or partially, as the user may desire. This valve turns ona pivot at 13.

It is obvious that the details of construction 6 is the bowl of thepipe.

may be varied while the essential features ofthese improvementsremainas,for example, the condenser may be made of a simple coil of wire or ofseveral coils'; butthe construction I have above described I considerthe best.

I am aware that a pipe hasbeen previously known in which a cell has beenmade below the bowl of the pipe to collect the oil of tobacco, and thatthis cell has been made capable of being emptied by means of a cupremovably attached to the bottom of it, and forming a part thereof. Itis obvious that this arrangement is very objectionable, from the factthat it involves the necessity of a perfectly-fittin g j oint betweenthis removable cup andthe bowl; and, even if so constructed, it involvesgreat trouble and inconvenience in keeping such a joint clean, while inmy arrangement no close fitting of the partition is required, and theoutside of the pipe is not smeared by the leaking or smearing of thelining constructed as described, in'combination with the removablepartition, substantially as and for the purpose set forth.

3. Providing the stem with a valve which may be opened and closed atpleasure, as set forth.

I ANDREW D. MILNE.
